HGY17 concrete spreading machine is a spreading equipment used in conjunction with concrete pumps for concrete pouring operations during construction, suitable for any concrete building such as buildings, bridges, roads, foundations, etc. The use of concrete fabric can fully utilize the working efficiency of concrete pumps, improve pouring quality, and reduce labor intensity.The HGY17 concrete laying machine consists of a laying arm assembly, a rotating device, upper and lower supports, a chassis, concrete pipelines, a hydraulic system, and an electrical control system. The fabric arm is a three section box structure, which is extended and folded by a hydraulic system. When combined with a rotating mechanism, it can transport concrete to the required construction surface. The hydraulic system is equipped with a safety relief valve to prevent overloading of the working mechanism. The working oil cylinder is equipped with a hydraulic lock to ensure construction safety. The electrical control system can achieve control panel operation and wired operation. The interlocking function between each operation mode also ensures construction safety.
